2017-03-27Add a no_native option wherever there is an on_loadKostis Sagonas
This is a poor man's solution that allows to build and test the system with all files compiled to native code simply by setting the ERL_COMPILER_OPTS environment variable. Better solutions, like automatically setting the no_native option whenever the compiler sees an on_load attribute, obviously exist but require more time to implement.

2017-03-20crypto: Deprecate crypto:rand_uniform/2 as it is not cryptographically strongIngela Anderton Andin
rand module should be used if not cryptographically strong is required. If cryptographically strong is required, new cryptographically strong functions should be added to crypto.

2016-09-28Support using OpenSSL in FIPS modeDániel Szoboszlay
FIPS mode support needs to be enabled at compile time, by configuring Erlang/OTP with --enable-fips option. In FIPS mode the non-FIPS algorithms are disabled and raise error notsup. The supported protocols list is properly updated in FIPS mode to advertise only the enabled protocols. FIPS mode is off by default even if Erlang/OTP was built with FIPS support. It needs to be turned on at runtime. The official approach is to set the fips_mode application environment parameter of the crypto application to true. This would turn FIPS mode on when the NIF is loaded and would prevent loading the module on error. Another method is provided via the crypto:enable_fips_mode/1 function, but it is not recommended to be used in production, as it won't prevent the use of the crypto module in case of an error, and would risk OpenSSL crashing the emulator. It is very useful for test suites however that need to check both validated and non-validated functionality. This commit is based on commit 00b3a04d17a653b4abddeebd6dd8a2c38df532d0.
2016-09-28Fix erlang:error/2 calls in crypto.erlMagnus Henoch
Make all calls to erlang:error/2 specify the actual argument list of the function. This ensures that the stacktrace contains the correct arity of the function where the error occurred.

2016-07-30crypto:cmac calculating the Cipher-based Message Authentication CodePetr Gotthard
The ERL-82 issue requests a way to calculate a CMAC in Erlang. The AES128 CMAC is standartized in RFC 4493 and used e.g. for message authentication in the LoRaWAN networks. The CMAC is implemented by OpenSSL since v1.0.1, but as @IngelaAndin stated in response to the ERL-82, the current crypto implementation does not include functions that call those OpenSSL cryptolib functions. This commit introduces a new function `crypto:cmac` that calls the corresponding OpenSSL functions and calculates the CMAC. Only the cmac_nif is implemented. The incremental functions (init, update, final) are not provided because the current OpenSSL does not allow custom memory allocators like `enif_alloc_resource`. The Erlang user guide states that at least OpenSSL 0.9.8 is required, so I added few #ifdefs so the code is compatible with all versions. However, the OpenSSL pages say that the pre-1.0.1 versions (0.9.8 and 1.0.0) are no longer maintained. Even the 1.0.1 will be retired by Dec 2016. Hence I believe that adding a 1.0.1-only function like CMAC should be OK.
2016-04-25crypto: Deprecate rand_bytes/1Ingela Anderton Andin
OpenSSL has deprecated the function RAND_pseudo_bytes used by crypto:rand_bytes/1, so this function is now deprecated in OTP too. rand_bytes/3 also used this function, but was not documented so we can remove it right away. This commit also removes the fallback in generate_key to use rand_bytes/1 if strong_rand_bytes/1 throws low entropy. This is a potential incompatibility but we think it is desirable as crypto should provide cryptographically secure functions.

2015-11-17crypto: Refactor nif code to use EVP interfaceSverker Eriksson
Using the generic EVP_* API makes it possible to unify algorithm-specific nif functions to a single generic function. Effectively the same change that took place on the Erlang API in R16B01 is now applied to the C code. The old implementation using the low-level API is kept for compiling against old OpenSSL, as parts of the EVP API were introduced in OpenSSL 1.0.0. There are various minor improvements as well: - supported algorithms are now provided by the nif code (not a mix of the C and Erlang code) - remove unnecessary variables and macro definitions Most of the changes in this commit comes from Dániel Szoboszlay https://github.com/dszoboszlay/otp/commit/07f7056f955b324df4ace which is part of his 'fips' branch. Now also rebased on master branch.

2014-03-20Introduce runtime_dependencies in .app filesRickard Green
Most dependencies introduced are exactly the dependencies to other applications found by xref. That is, there might be real dependencies missing. There might also be pure debug dependencies listed that probably should be removed. Each application has to be manually inspected in order to ensure that all real dependencies are listed. All dependencies introduced are to application versions used in OTP 17.0. This since the previously used version scheme wasn't designed for this, and in order to minimize the work of introducing the dependencies.

2014-02-18Fix library application appup filesTobias Schlager
As discussed in issue #240 *all* OTP library applications use the '.*' wildcard as up and down version. This makes library applications always up- and downgradeable. Using the wildcard version obsoletes all maintenance tasks regarding library applications' appup files. Additionally, it prevents upgrade problems caused by automatically included application dependencies when using reltool to create releases. Missing copyright headers are now consistently present.
